introduction

Hi there,just like to introduce my self i am coming up to 52 years of age and this is my first audi and i love it, sorry forgot to say it is an A4 1.8t sport avant.i have found it to be very well put together and an absolute  pleasure to drive the only thing i would say is on my insurance it states that my car is (163 bhp) but i had a vw passat  tdi estate (130 bhp) before this car and it felt quite a bit more powerful on exhilaration than my audi so i was just wondering if my car is (163 bhp ) or is it one of the other power plants that they fit in them ? could anyone advise how i could find out witch one it is ? as it dosn't tel me on the log book many thanks kev.

p.s sorry to start with a question but i have found car forums to be a wealth of information to a none mechanic like my self.
